To provide an oil drain for the supercharger, it is nec-

essary to make a hole in the oil pan. It is best to

punch the hole rather than to drill it.

Remove paint from the area around the hole.

Mark the oil pan 5/8" down from the oil pan

mounting rail on the driver’s side of the engine.

Measure forward 3/4" from the first bolt on the

side of the oil pan. (See Fig. 3-a.)

Use a small center punch to perforate the pan and

expand the hole. Switch to a larger diameter

punch and expand the hole further to approxi-

mately Ø9/16". Most punches are made from

hexagon material and may be placed in a socket

with an extension to make this procedure easier.

Tap the hole with a 3/8"NPT tap approximately 1/4"

deep. Pack the flutes of the tap with heavy grease

to hold chips. Use a small magnet to check for any

stray chips.

NOTE: This method of rolling over the lip of

the hole and tapping it works very

well if carefully done and should

cause no problems.

Thoroughly clean the threaded area. Apply a small

amount of silicone sealer or teflon paste to the

new threads. Apply more sealer to the 3/8"NPT

hose fitting and secure in the hole. Make sure a

seal is formed all around the fitting. (See Fig.

3-b.)

Drain the engine oil and change the filter.
